BIOLOGICAL MILK SAMPLES (Farm Bottled Milk)
Eleven samples of Tuberculin Tested Milks were taken for
biological examination. In all cases the guinea pigs inoculated
with the milks failed to show any signs of a tuberculous infection
on post mortem.
ICE CREAM
Registrations. At the end of 1952, a total of 182 premises
had been registered for the sale of ice cream in accordance with
Section 14 of the Food and Drugs Act 1938 and on six of these
premises ice cream could be manufactured. The quantity of ice
cream manufactured in the Borough still continues to decline.
During the year thirteen new applications for the registration
of premises for the sale of ice cream were received and
granted.
(A)
Bacteriological Sampling of Ice Cream
One hundred and two samples of ice cream were taken for
provisional grading and bacteriological examination.
The following table shows the provisional grading percentages for the year 1952 and for comparative purposes the results obtained from samples in 1951.
| 1952 Grading of samples | 1951 Grading of samples | ||||
|---|---|---|---|---|---|
| Grade 1 | 63 Samples | 61.76 | Grade 1 | 94 Samples | 74.60 |
| " 2 | 30 " | 29.41 | " 2 | 25 " | 19.84 |
| " 3 | 6 " | 5.88 | " 3 | 5 " | 3.96 |
| " 4 | 3 " | 2.94 | " 4 | 2 " | 1.58 |
| 102 " | 126 " | ||||
It is gratifying to report that the bacterial purity of the
ice cream sold in the Borough during the year has been maintained
at a relatively high standard.
The results achieved favourably compare with the recommendations
made by the Ministry of Health which require that over a
given period 50% of the vendors samples should fall into Grade 1,
80% into Grades 1 or 2, not more than 20% into Grade 3 and none
into Grade 4.
